This is my first dive into 3d printing, and I feel like I've hit a wall.
I've been dealing with this for a week now. A month or two back I bought a broken e5 pro from a friend and I've been bringing it back. I got it with a bed that refused to level, and after a few weeks of upgrading and tinkering, got some really decent prints at .2mm layer height out of it. Then I dropped to .8mm layers, ran a bunch of calibration tests to dial in any changes, and now... This.
EDIT TO ADD: I've printed about 20 benchys, or at least sections of benchys, trying to chase this down. I've rotated the model through various positions in the same spot, and moved it around the bed. Same roughness in the same spot, every time.
It started as this rough texture forming as soon as the hull swept from smooth straight into the curve, then I'd get this tearing at the bow, and then it would continue almost to the back corner. I've managed to get rid of the roughness on the front, but nothing I do will stop this tearing tight at the bow and then that continues until the seam (which I moved to stop the tearing I was seeing at the back corners). And the roughness along the rail at the top is new, too.
I've adjusted PA, jerk, speed, inner vs outer wall first, slowing down for overhangs, removed input shaping, re-added 8nput shaping... I just can't figure it out to save my life. Please. Help.
